power commanders ?

[batunball]

Hi do power commanders set up on a rolling road really make a big difference to 1000cc bike. Or can you just fit one and down load a map to suit and still feel a big difference?

[hmmmnz]

yes, yes and sometimes

it generally makes the bike run alot smother,
you can download a map that is close to your setup, but how close??
every bike is different, you won't know if you are running lean in places unless you dyno it,


if you are going to fork out alot of cash for a power c then you may as well spend a wee bit more and get it properly set up for your bike

Cost of the PC was around £280 when I bought mine a few years back. The place I took it to supplied, fitted and mapping it for £400. That was an hour or so fitting, then three or four hours on the dyno.

If you're forking out for a PC, may as well map it IMHO.

im looking at getting an SP1 in the next few week's and hear they really need a power commander to make them rideable at lower rpm's, 3 to 4 hours on a dyno with an sp1 is likely to drain the worlds oil resources, who pays for all this fuel?

On early Fuel Injected hondas, the map on the ECU was SHOCKING to say the least. It used to always hunt at low revs in low gears in town, making for a lot of work.

The power commander, on a generic map seemed to eliminate the low end jerkiness on my 929. But, there is no substitute to getting the fuelling mapped out properly to how you want it. If anything, it liberates the midrage as a result any factory-set flat spots to get through emissions.

Depending on the bike some PC3's are just fuel but R1's are both fuel & ignition. If you are looking for extra power change the exhuast first.

You can just install a map and it can make a difference.

If you are going to get it Dyno'd make sure the valves, throttle bodies are in sync etc first then dyno it.
Also ask them to do a couple while in on the bench ie a max power and fuel economy it wont cost much more.

I made my own map using ones that were available then adjusted the factors to suit me.

My present map is standard upto 5000rpm then racer from there on I also use the accelerator function in the lower rev range so if I snap the throttle quick I get an 20% more fuel for the first 5 seconds then it goes back to standard which helps with fuel consumption.

If you want to something to give you loads of extra power don;t bother, if you want something to smooth your bike out and make it run better then buy it. I got one on my TDM and with a downloaded map it was miles better.

If it's a suzuki then they don't need a power commander, you can edit the ECU directly via a yoshi box etc.

I dont know if it still applies, but Dynojet used to charge a set fee of £90 to do a custom map, regardless of how long it took.

Thanks for all your replys.Next question can any one recommend a good dyno center in west yorkshire thanks.

Anyone know if there is a big difference (other than connecting to pc via USB or serial) to the PCIII and PCIII USB???
